Thought for the day: Jpg vs RAW – which is more honest?
All images start out as RAW data. When you save a JPG the camera is converting the image internally into a JPG and is applying many transforms to the RAW data to adjust the color temperature, color correction, contrast, saturation, exposure and much more to fit what the camera engineer and marketing like rather than what was really there. The simple RAW conversions are designed to have a lower contrast and be duller than the simple JPGs. And JPGs from some vendors get a fair bit more extreme than others in their JPG conversions. Which is why some people say “What wonderful color my camera captures”.
Want to do a horrible experiment? Make an image for print that is mostly one color. Now have the printing company print it with their automatic color adjustments. Cry at the results… (I did that accidentally, once).
